Intermittent ignition problem with my 2005 Toyota Camry LE.

I have had the starter replaced, the alternator, and battery checked, and still have an intermittent ignition problem. My particular model has the Toyota ignition inhibitor and I think the issue is connected to that but the dealer mechanic says that it should have nothing to with it.

If your battery is over 5 years old that may be your entire problem. My
kids car had the same issue. Replaced everything you have replaced
and had the battery checked. Battery tested fine. Problem
remained...changed out battery, problem solved. Never trust those
battery load testers....

Update: When I purchased my Camry in 2006, Toyota was installing an
anti- theft device they called "Protection Plus". Essentially it is an ignition
inhibitor wired to the starter, and in order to start the car you need to
engage the inhibitor (turn on the radio, roll the driver-side window down,
turn on hazard lights, something like that). If the inhibitor is not engaged
the car will not start let alone turn over. I took the car back to the dealer
that sold the car to me and asked if this could be my problem, they said
maybe but that they would replace the component free of charge. After
the replacement the car runs perfectly. Thanks to everyone for all of the
suggestions, I will definitely keep them in mind should something else go
wrong in the future.

Does it run worse in the wet spray the ing coil down one at a time
If it misses when you spray the coils rhey have a short
The get little holes in the bottom of the coil over the spark plugs and
short against the head and misfire at the plug
